Mark Wahlberg Goes Shirtless & Gets Caught Grabbing Himself

Actor Mark Wahlberg has never been one to be shy when it comes to showing off his rocking physique. The 47-year-old is giving dudes half his age a run for their money when it comes to staying in tip top shape and looking fantastic while doing so (Hugh Jackman is another great example of this.)

He was recently spotted out at a lake with a friend in Cape Cod, where the Boogie Nights star was (of course) shirtless and seemed to be having a great time while there.

The paparazzi also got a couple of good shots of him getting very "handsy" with himself, which evoked the same type of grab he did many moons ago when he posed for Calvin Klein underwear (Nick Jonas did something similar a couple of weeks back).
